Abstract

A fishing line guide includes a fishing line guide section guiding a fishing line along a fishing rod, a first leg portion extending in a first direction from an end portion of the fishing line guide section and having a fixed portion disposed at a tip, and a second leg portion branching from either one of the end portion of the fishing line guide section and the first leg portion to extend in a second direction and having a fixed portion disposed at a tip are integrally configured, the fishing line guide including a first fiber-reinforced resin sheet, a second fiber-reinforced resin sheet, and a third fiber-reinforced resin sheet, each sheet including a laminated structure with a flat bonding surface, the laminated structure including a plurality of sheet-shaped synthetic resins containing reinforced fibers that are laminated together.

First claim

The invention claimed is:

1. A fishing line guide comprising a fishing line guide section guiding a fishing line along a fishing rod, a first leg portion extending in a first direction from an end portion of the fishing line guide section and having a fixed portion disposed at a tip, and a second leg portion branching from either one of the end portion of the fishing line guide section and the first leg portion to extend in a second direction and having a fixed portion disposed at a tip are integrally configured, the fishing line guide comprising:
a first fiber-reinforced resin sheet;
a second fiber-reinforced resin sheet;
a third fiber-reinforced resin sheet;
each sheet comprising a laminated structure with a flat bonding surface, the laminated structure comprising a plurality of sheet-shaped synthetic resins containing reinforced fibers that are laminated together,
wherein the laminated structure of the first fiber-reinforced resin sheet forms the fishing line guide section and the first leg portion,
the laminated structure of the second fiber-reinforced resin sheet is fixed to the first fiber-reinforced resin sheet via their flat bonding surfaces between the fishing line guide section and a branching position from which the second leg portion branches, and
a branching gap member disposed in a gap that is formed at the branching position and is surrounded by the first fiber-reinforced resin sheet and the second fiber-reinforced sheet, the branching gap member being positioned at the branching position and surrounded by each of the flat bonding surfaces of the first fiber-reinforced resin sheet and the second fiber-reinforced resin sheet,
wherein the first direction is a forward direction along the fishing rod,
the second direction is a backward direction along the fishing rod, and
the branching gap member is formed by a prepreg in which a plurality of reinforced fibers are arranged in a row and impregnated with a thermoset resin.

2. A fishing line guide comprising a fishing line guide section guiding a fishing line along a fishing rod, a first leg portion extending in a first direction from an end portion of the fishing line guide section and having a fixed portion disposed at a tip, and a second leg portion branching from either one of the end portion of the fishing line guide section and the first leg portion to extend in a second direction and having a fixed portion disposed at a tip are integrally configured, the fishing line guide comprising:
a first fiber-reinforced resin sheet;
a second fiber-reinforced resin sheet;
a third fiber-reinforced resin sheet;
each sheet comprising a laminated structure with a flat bonding surface, the laminated structure comprising a plurality of sheet-shaped synthetic resins containing reinforced fibers that are laminated together,
wherein the laminated structure of the first fiber-reinforced resin sheet forms the fishing line guide section and the first leg portion,
the laminated structure of the second fiber-reinforced resin sheet is fixed to the first fiber-reinforced resin sheet via their flat bonding surface, the second fiber-reinforced resin sheet branching to a branching position from which the second leg portion branches,
the laminated structure of the third fiber-reinforced resin sheet extends from the first leg portion to the second leg portion through the branching position and is fixed to the first fiber-reinforced resin sheet and the second fiber-reinforced resin sheet via its flat bonding surface, and
a branching gap member disposed in a gap that is formed at the branching position and is surrounded by the first fiber-reinforced resin sheet, the second fiber-reinforced sheet, and the third fiber-reinforced sheet, the branching gap member being surrounded by each of the flat bonding surfaces of the first fiber-reinforced resin sheet, the second fiber-reinforced resin sheet, and the third fiber-reinforced resin sheet and positioned at the branching position,
wherein the first direction is a forward direction along the fishing rod,
the second direction is a backward direction along the fishing rod, and
the branching gap member is formed by a prepreg in which a plurality of reinforced fibers are arranged in a row and impregnated with a thermoset resin.

3. The fishing line guide according to claim 2 , wherein a bending radius of the third fiber-reinforced resin sheet reaching from the first leg portion to the second leg portion through the branching position is larger than a layer thickness of each of the first fiber-reinforced resin sheet and the second fiber-reinforced resin sheet.

4. The fishing line guide according to claim 1 , wherein the branching gap member is adhered to each of the flat bonding surfaces of each of the first, second, and third fiber-reinforced resin sheets.

5. The fishing line guide according to claim 2 , wherein the branching gap member is adhered to each of the flat bonding surfaces of each of the first, second, and third fiber-reinforced resin sheets.

6. A fishing rod for fishing comprising a plurality of fishing line guides and an annular fishing line guide section, a first leg potion extending in a first direction from an annular end portion of the fishing line guide section and having a fixed portion disposed at a tip, and a second leg portion branching an extending in a second direction from either one of the annular end portion of the fishing line guide section and the first leg portion and having a fixed portion disposed at a tip are integrally configured are disposed, the fishing rod comprising the fishing line guide including:
a first fiber-reinforced resin sheet;
a second fiber-reinforced resin sheet;
a third fiber-reinforced resin sheet;
each sheet comprising a laminated structure with a flat bond surface, the laminated structure comprising a plurality of sheet-shaped synthetic resins containing reinforced fibers that are laminated together,
wherein the laminated structure of the first fiber-reinforced resin sheet forms the fishing line guide section and the first leg portion,
the laminated structure of the second fiber-reinforced sheet is fixed to the first fiber-reinforced resin sheet via their flat bonding surfaces between the fishing line guide section and a branching position from which the second portion branches, and
where the laminated structure of the third fiber-reinforced resin sheet extends from the first leg potion to the second leg portion through the branching position and is fixed to the first fiber-reinforced resin sheet and the second fiber-reinforced resin sheet via its flat bonding surface; and
